"All fowls that creep, going upon all four, shall be an abomination unto you.....but all other flying creeping things which have four feet, shall be an abomination unto you." Leviticus 11:20,23
There are no four legged birds (except mutations) and as far as I know, there aren't any four legged insects. Why would God have a prohibition against something that doesn't exist?
Reading this has shaken my faith in the Holy Scriptures.
